From a social science perspective, various studies have explored identity sharing behavior in social network sites and the
risk of over exposure (notable examples are [1]}, [2]}, [3]}, [4]}).
Research studies have shown that users in
online environments rely on a variety of cues to make
determinations about one another; however, all these cues
are not deemed equally credible. For instance, Goffman
[5]} notes that identity cues can be intentionally given or
unintentionally revealed, and that humans are more likely to
place greater weight on those cues that are perceived to be unintentional
as opposed to strategically constructed. This ability to
engage in deceptive self-presentation online is compounded
when users do not share a social network and
therefore have less access to Òinformation trianglesÓ such as
mutual friends who might confirm or deny information.
Donath [6]} argues that a shared social
network can provide explicit or implicit verification of
identity claims. Therefore, as highlighted in [4]}, a highly connected network such as Facebook should
encourage more truthful profiles, or misrepresentations that
are playful or ironic as opposed to being intentionally
deceitful.
